When you're in the middle of a longer workout or race, your body is constantly jettisoning critical electrolytes that are key to good blood hydration. Clif Shot's Electrolyte Hydration Drink Mix allows you to fortify your water so your body's cooling system keeps doing its job. With 250g of electrolytes and a nice, balanced boost in carbs and sugars (19g/10g respectively), you'll get a recharge in the two most important areas for performance: hydration and energy.
